A 41 year old woman presented with community acquired
pneumonia (CAP) which failed to resolve following treatment with
amoxycillin and cefaclor prior to referral. Quantitative culture of
sputum revealed a pure growth of Haemophilus
parainfluenzae and, following antibiotic susceptibility testing
of the isolate, ciprofloxacin was prescribed resulting in resolution of
the infection. Immunological investigations showed that the patient had
a high titre of H parainfluenzae specific
IgM. The combination of a pure growth of H
parainfluenzae, a response to appropriate antimicrobial therapy,
and the presence of a specific antibody response indicated that this
organism had a pathogenic role in the patient's pneumonia and should
be considered in the differential diagnosis of CAP.
